There are several ways to reduce network congestion. Subnetting and adding routers will break up broadcast domains and traffic. Adding VLANs will do the same while adding security. Upgrading the speed of NICs and wiring, i.e. moving from 10BaseT to 100 or 1000, will reduce congerstion as will moving from half duplex transmissions to full duplex transmissions.
To reduce congestion & optimize the IP address space.

what are the congestion prevention policy on network lay
The techniques include End-system flow control, Network congestion control, Network based congestion avoidance and Resource allocation.
congestion is Traffic in excess of network capacity. it occurs network layer and it is one of the function of network layer.
Increase the bandwidth.
at the network layer, congestion control mechanism takes place
Increase the bandwidth.
It don't control congestion that is up to the routers and gateways as they are the ones that look at the traffic and figure out the best way to send something over the internet.

Congestion control does ensure that the network does not become saturated at any one point. This ensures that there is no compromise in the quality of service.
When too many packets are present in a subnet, performance degrades. This situation is called Congestion. Update: In any network when there is too much the data traffic at a node that the network slows down or starts loosing data, it is known as network congestion. It degrades quality of service and also can lead to delays, lost data or e.g. dropped calls on a telephone network. - Neeraj Sharma when excess of data travels in a subnet or in node there will be a loss of data, this excess flow is know as network congestion.This demotes the performance in network e.g.improper delivery of fax
